IMPROVEMENT IN SHOEMAKERS JACKS.

Specification forming part of Letters Patent No. 119,675, dated October,1871.

To all whom t may concern:

Be it known that I, FRANZ WnrssENBoRN, of Egg Harbor Oity, in the countyof Atlantic and State of New Jersey, have invented a new and ImprovedShoemaliers7 Jack; and I do hereby declare that the following is a full,clear, and eX- act description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification. I

Figure l represents a side elevation, partly in section, of my improvedshoemakers7 jack, the line o c, Fig. 2, indicating the plane of section.Fig. 2 is a detail transverse section of the same on the line k k, Fig.l.

Similar letters of reference indicate correspond ing parts.

My invention consists in the improvement of shoemakers jacks, ashereinafter fully described and subsequently pointed out in the claim.

A in the drawing' represents the frame of the jack, secured at its lowerend to the floor of the apartment in which it is put up. B is acrossbeam, journaled at its ends in the upper end of the frame A. C isthe jack, swiveled by a bolt or pin, D, to the crossbeam. E is the postfor supporting the last F. It is iitted into the jack O in such mannerthat it may be swung more or less outward or inward, a spring, a, whichis concealed within the jack, holdingl it inward-that is, vertical tothe face of the jack. Gr is the rest for supporting the toe of the last.It is provided with a slotted plate, I), projecting toward the post Eand fastened to the jack by a bolt, d, that penetrates said plate b. Therest is thus adjustable on the jack to admit of longer or shorter lasts.The plate b, projecting under the last, is out of the way of threads orother things used in the manipulation of boots or shoes. One end of thecross-piece B carries a notched tooth or segment, e, into which aspring-bolt, f, sliding in a post of the frame A, is locked for securingthe crosspiece in any desired position. A handle, g, for withdrawingthebolt from the segment, projects downward, so that the shoemaker canreach it with the knee, permitting him thus to turn the last to theright or left without taking the han ds from the work.

The last can, on the horizontal axis of the crossbeam B and on thevertical axis of the swivel-jack, be conveniently turned in eitherdirection to bring the boot or shoe in the most convenient position forhandling. The bolt d, it will be seen, passes only through the metallicbottom plate lzy of the jack, said plate having a cylindricaldepression, i, ttin g into a cavity of a plate, j, that is secured inthe cross-beam. When the jack is turned on the cross-beam it turns inthe plate j, leaving the bolt entirely undisturbed, and preventingthereby the jarring and working' oft of the nut atthe lower end of saidblock.

H is a receptacle or drawer for holding' tools, ndings, Sto.

VHaving thus described my invention, I claim as new, and desire tosecure by Letters'Patent- The notched tooth e, spring-bolt j', and leverg, arranged with respect to the frame A and beam B, as and for thepurpose specified.
